Title: Surface area variable radiator for artificial satellite
Inventor: KITADE KENJI
IPC: B64G1/50
Filed: 1992-02-04
Abstract: PURPOSE:To automatically control the temperature of equipment mounted in an artificial satellite without consuming electric power. CONSTITUTION:A sealed bellows radiator 1 having expansibility is attached to the heated face of a mounted equipment 5 for which temperature is controlled. Changes in the heat of the mounted equipment 5 causes the bellows radiator 1 to expand or contract in response to changes in the internal pressure caused by the emittance and storage of hydrogen gases contained in a hydrogen storage alloy 2 installed in the bellows radiator 1. This constitution allows the extent of heat radiation in space caused by the bellows radiator to be automatically adjusted and enables the temperature of the mounted equipment 5 to be controlled without a heater.

Title: Exhaust gas by-pass device of engine using alkohol-modified gas fuel
Inventor: NISHI KAZUNORI
IPC: F02M27/02
Filed: 1982-02-09
Abstract: PURPOSE:To suppress deterioration of catalyzer by opening an exhaust gas by- pass valve regardless of temp. of the alkohol modifier, while the engine is in operation at deceleration, and by avoiding temporary overheat of the modifier at the time of deceleration. CONSTITUTION:According to this arrangement, an exhaust by-pass valve 36 is normally closed to supply most of the exhaust gas from an engine 20 to an alkohol modifier 22, but the valve 36 is opened in conformity to a controller 39, if the temp. of the modifier 22 exceeds a certain set value because of subsequent high-load operation, so as to hold the modifier 22 at an approx. constant temperature. At the same time, it is so judged that the engine 20 is in decelerative operation when the amount of accelerator stamping sensed through an accelerator sensor 38 is below preset value, so as to permit the controller 39 to feed a valve opening signal to the exhaust by-pass valve 36 through a servo valve 45 regardless of the temp. of the modifier 22. Thus the rate of flow of the exhaust gas fed to the modifier is decreased.

Title: One-side electrostatic recorder
Inventor: TAN GIYOKUKOU
IPC: G03G15/05
Filed: 1980-02-19
Abstract: PURPOSE:To form excellent electrostatic latent images by coupling a low-voltage side circuit and high-voltage side circuit, consituting a driving circuit, together through a capacitor, and by applying a power voltage to an electrode by turning on the transistor of the high-voltage side circuit in electrode drive. CONSTITUTION:While auxiliary voltage VC is applied to auxiliary electrode 1C, recording voltage VB is applied to recording electrode 1B and because R2 is much greater than R11 and R12, auxiliary voltage VC is applied to point P via electrostatic capacities C11 and C12 at the moment, so that potential VP at point P will nearly be eual to VC. Then, potential VP drops as shown in the figure because electrostatic capacities C11 and C12 are charged by a formed charging circuit via resistance R2. Therefore, applying recording voltage VB on the application of auxiliary voltage VC applies high voltage VC-VB to gap G at the moment, causing discharge. As a result, electrostatic capacity C2 of dielectric layer 2B right over recording electrode 1B is charged to form an electrostatic latent image.

Filed: 1985-02-04
Abstract: PURPOSE:To obtain much superior recording and reproducing characteristics while a recording film is a single layer by dispersing pulverous metallic particles and org. material into a metallic carbide matrix thereby constituting the recording film. CONSTITUTION:The recording film 12 the pulverous metallic particles and org. material in the metallic carbixe matrix is formed in one stage by using plasma. Bubbles 13 are formed on the film 12 by irradiation of a laser beam for recording. Reproduction is executed by irradiating the laser beam of the intensity of 1/5-1/10 the intensity of the beam for recording. The irradiated reproducing beam is diffracted in conformity with the bubble shape in the part where the bubbles are formed and therefore the intensity of the reflected or transmitted light is considerably different from the intensity of the reflected or transmitted light in the flat part where no bubbles are formed. The reproduction of good CNR is thus made possible if the intensity other reflected or transmitted light is detected by a photodetector.
